I believe they are both.
skeletal muscles are voluntary muscles.
involuntary muscles can't control consciously, but voluntary muscles can.
Smooth muscles are involuntary, as are cardiac muscles. Only skeletal muscles are voluntary.
Heart muscles are involuntary.
voluntary, you control what it does.
The brainstem controls the involuntary muscles and the cerebellum controls the voluntary muscles.

Voluntary muscles are what you have control over. Like your skeletal muscle are usually voluntary. Involuntary muscles are what you have no control of. Like your smooth and cardiac muscles you have no control of. The difference between voluntary and involuntary muscles are voluntary muscles you have control of and involuntary you have no control of. Hope this answered your question.
They are involuntary muscles.
Voluntary muscles are the ones you can control with your mind and the involuntary ones you cannot control, they do their jobs automantically.
Muscles vary throughout the body by voluntary and involuntary, voluntary is the muscles you can move and involuntary is the muscles you can't move.
They are involuntary muscles.
